Ch.1
Definition of mass
What is the amount of matter the object contains
Define compound
What is 2 or more elements hooked together to form something new
Define atomic mass
The average mass/matter of 1 atom of an element
(in AMU)
Define valence electrons
Electrons in the outermost shell that interact and react with other atoms
How many bonds can hydrogen make
What is the amount of space something takes up
Example of a compound
What is H20, NaCl, etc?
The three subatomic particles
Protons, neutrons and electrons
Molecular covalent bond
When 1 or more pairs of electrons are shared between 2 atoms
What is a diagram that shows how atoms are arranged and connected
Define water displacement
what is changing volume of water to determine the volume of a irregular shaped object
Define LCM
What is Matter cannot be created or destroyed, only changed in form
Electrons effect on atomic mass
They are too light to have an affect on mass.
Difference between cations and anions
What is a positive ion and a negative ion
Describe the octet rule
When non-metal atoms combine, they do so that each gets 8 by sharing
Summarize the scientific method
Color of copper as a solid
What is orange/orange brown
Subatomic particle around nucleus of atom
Electrons
Describe a transition metal
What are a group of metals that are found in the middle of the periodic table.
A smell that contains nitrogen, but no oxygen
Amines
Density formula
What is D=m/v
Formula for copper nitrate
What is Cu(NO3)2
Complete definition of isotopes
what is each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nucleus
Describe the ROZC
When a metal + non-metal bond, the total compound charge must equal 0
EDT
Electrons with the same charge repel each other and exist as far apart in a 3-D space as possible
